Description

Technical area

The present invention relates to a method and apparatus for selecting one of at least two traffic networking devices as a primary device, a computer program product with instructions therefor, and a computer-readable medium on which the computer program product is stored.

State of the art

In recent years, the application of transportation networking has increased. Traffic networking here means V2X communication, i.e. vehicle-to-everything communication, in which electronic communication between traffic participants takes place. This can, for example, be in the form of vehicle-to-vehicle communication (V2V), vehicle-to-road (V2R), vehicle-to-infrastructure (V21), vehicle-to-network (V2N) and vehicle-to-person ( V2P). The transport network is part of C-ITS (coorperative intelligent transport system). Such a traffic network allows communication between vehicles as well as communication between a vehicle and pedestrians or infrastructure elements on the side of the road. The V2X devices can be on board vehicles. However, these can also include portable electronic devices (PED for portable electronic device), such as smartphones, key fobs that use a passive transponder in the form of an RFID token, but also smart watches.

Due to the use of a large number of transport networking devices, selection conflicts may arise. For example, the vehicle's own traffic networking device can be located in the vehicle and at the same time a retrofitted traffic networking device and also, for example, a smartphone from a vehicle occupant. When using a keyfob, a pedestrian can also carry a smartphone that is suitable for traffic networking in addition to the keyfob. This device conflict, either in the vehicle or the pedestrian, raises the question of decision making as to which of the devices will be used as the primary traffic networking device.

From the US 10,462,225 A retrofit communication device is known, which can be retrofitted to a vehicle. The primary goal is traffic network communication for vehicles not yet equipped for this purpose. As a result, only a predetermined device can then be used in the vehicle.

In terms of multi-device connectivity, the KR 101 430 886 known, in which communication modules are present for communicating with a variety of medical devices. This involves selective communication between communication modules of different frequency bands and external devices.

From the WO 2006 116 191 A1 A processor in a mobile device is known for establishing a network connection to a server on a first network while supporting a call on a second network. In the US 2009 0 170 431 A1 Information for the wireless connection readable by a mobile device may be stored, wherein first connection information includes data for supporting the establishment of a first wireless connection between the mobile device and the first wireless device and second connection information includes data for supporting the connection of a second wireless connection between the mobile device and the second wireless device. Furthermore, the Vivo Dual WIFI Acceleration Technology (https://www.gsmarena.com/oppo_vivo_dual_wifi-news-38203.php and https://www.gizmochina.com/2019/07/18/vivo-dual-wifi-acceleration -technology/), in which the network source or frequency band can be dynamically switched during use. The smartphone chooses the faster network connection or is the smartphone connected to two different networks with different frequencies at the same time.

The prior art also includes: US 2017 / 00 480 80A1 known which discloses a traffic networking device, also wireless, and a method for connecting this device to the vehicle both wired and wirelessly. A method for automatically connecting personal devices to a vehicle is available US 8750832B2 known. In the process from the US 2019 / 0096243 A1 determines whether a vehicle already has active traffic networking communication, the function of the traffic networking device is taken over by the vehicle and a transition from the vehicle to a pedestrian occurs if the proximity to the vehicle is not present.

Furthermore, the fact examined by the inventors must be taken into account that one traffic networking device may represent the best option for a first functionality, while another traffic networking device may represent the best option for a second functionality. Here, the first functionality can be, for example, a new communication standard that is available via a smartphone in the vehicle, while the traffic networking device installed in the vehicle can, for example, provide vehicle speed data with higher accuracy as a second functionality. Furthermore, the functionality can also relate, for example, to the shielding of a device or antenna in a certain direction, to different update statuses of the devices and/or to the computing load and/or the computing power in relation to other functions.

Description of aspects and embodiments of the present invention

Methods and devices for selecting one of at least two traffic networking devices as a primary device for carrying out traffic networking communication with respect to a traffic user are described in more detail below in accordance with the aspects and their variants and in accordance with the exemplary embodiments of the present invention.

The present invention took into account that smartphones are increasingly receiving more functions and that they are also suitable as a device for traffic communication. Advantages of the 5G standard for mobile phones include low latency, support for precise positioning and high transmission capacities, which enable secure data transmission even with a high device density. Smartphones with 5G functionality are therefore suitable for the accelerated introduction of traffic networking in vehicles, especially if smartphones are used for traffic networking communication instead of the special traffic networking units in vehicles.

However, the present invention is not limited to the use of smartphones as portable electronic devices (PED), but according to the present invention, any electronic devices such as laptop computers, tablets and electronic entertainment devices can be used as long as one Suitability for transport networking exists. This suitability can occur, for example, via direct wireless communication from these devices, or via wired communication with the vehicle.

The term “vehicle” is used below to refer to, for example, motor vehicles, buses, motorcycles, wheelchairs, electrically powered one-person vehicles such as Segway® Personal Transporters, bicycles, motor scooters or skateboards. “Pedestrian” is hereinafter referred to as a human user who is not currently using any of the vehicles defined above. Vehicles as understood by the present invention may or may not have an element of centralized decision making. Examples of a vehicle without a centralized decision-making element include older models, vehicles and skateboards where space limitations make such elements inconvenient.

The application of the present invention to a device and a method for selecting one of at least two traffic networking devices as a primary device for carrying out traffic networking communication with respect to a road user is not limited to the fact that at least two potential traffic networking devices are present in a vehicle, but A pedestrian can also carry two portable electronic devices suitable for traffic networking. An example is carrying a tablet computer and a smartphone at the same time, both of which have 5G communication capability.

The present invention has considered how to carry out the decision making process for traffic network communication. The decision to select the primary traffic networking device, which alone carries out the traffic networking communication in relation to a vehicle or in relation to a pedestrian, can be carried out by an algorithm, by the human or by a decision logic that is either present centrally, for example in the vehicle , or distributed to or present in any device.

The following features have been important in the development of the present invention: A method for detecting a change in transport mode is provided. This can be, for example, switching from one vehicle to another, switching from a vehicle to pedestrian mode or switching from vehicle mode to pedestrian mode. Furthermore, a large number of devices capable of transport networking can be detected. In the present invention, these are at least two devices, for example a plug-in traffic networking device provided in the vehicle and a portable electronic device (PED) that the user carries with him.

In the present invention, there may be a centralized or distributed decision-making algorithm for selecting the primary transportation networking device. Decision criteria can take into account the capabilities of the devices relevant to the transport network operation. The skills or preferences relevant to traffic networking can be exchanged among the traffic networking devices present in the vehicle or pedestrian or between the devices and the element for centralized decision-making. The decision found for future use can be stored centrally or distributed, i.e. in respective portable electronic devices. An exchange of information can take place via a human-machine interface (HMI) either on the portable electronic device or on a traffic networking device in the vehicle. For example, this may include presenting information to a human user and receiving input information from the user.

First aspect

A device for selecting one of at least two traffic networking devices as a primary device for carrying out traffic networking communication with respect to a traffic user according to the first aspect is shown in FIG 1 , 3 and 4 , which represent variants a, b and c, are shown.

A method for selecting one of at least two traffic networking devices that are executable according to variants a, b and c of the first aspect is in 2A shown. In 2A alternatives a, b and c differ in steps S4 and S5.

With the first aspect, it is possible to carry out a change from one type of vehicle to the next, for example from a motorcycle to a motor vehicle, with the second vehicle, or both vehicles, having a centralized decision-making system as an element for centralized decision-making. With the first aspect, it is further possible to make a change from pedestrian mode to vehicle mode, for example from walking to getting on a motorcycle, with the vehicle having a centralized decision system.

In the first aspect, the detection of the change in transport mode, for example from one vehicle to another or from pedestrian to vehicle, is carried out by taking into account the following factors: a change in the connections to the vehicle, a change in the kinematics, for example a speed of movement atypical for a pedestrian, a change in the use of portable electronic devices, such as launching a navigation application on a mobile phone.

In the first aspect, a centralized decision system is used, which is preferably present in the vehicle and to which every traffic networking device can be connected. This connection can be wired or wireless, for example. With a wired connection of portable electronic devices to the vehicle, for example, the portable electronic device can be charged in parallel. The detection of the plurality of traffic networking devices in relation to a vehicle or a pedestrian is performed when more than one traffic networking device is connected to this centralized decision system. The centralized decision system collects the identities, the capabilities relevant to transportation networking, and the preferences relevant to transportation networking, respectively, of all available transportation networking devices. Capabilities include, for example, traffic networking transmit power (the number of antennas, and output power), application software version and supported features related to traffic networking, position sensing performance (such as GNSS), available computing power, and remaining battery power. The preferences include, among other things, user preferences, such as the ability to access traffic only with respect to certain vehicles, preventing traffic connectivity while running entertainment applications such as playing YouTube movies, and device preferences, for example Use for transport networking only under the condition that the remaining battery capacity is 80%. With the centralized decision system, it is possible to determine the primary traffic networking device based on predefined rules and logic. If there is a known combination of known devices with known capabilities or preferences, the decision as to which of these devices is used as a traffic networking device is obtained from the central storage device, which is preferably also present in the vehicle.

After the decision is made, the decision about the use of the primary traffic networking device is transmitted to all devices and the primary traffic networking device begins its traffic networking operation. The identities, capabilities, preferences and also the decision regarding the primary traffic networking device are stored in a centralized memory, which is preferably also present in the vehicle.

Variants a, b and c in the first aspect differ in terms of human involvement in decision-making. In alternative a, humans are not involved in making the decision about the primary transportation networking device and the centralized decision system selects the primary transportation networking device based on predefined rules and logic. In variant b, the human being is not involved in the decision-making process, but is informed about the result via a human-machine interface (HMI). This interface can either be on board a vehicle or can be displayed on a portable electronic device. In variant c of the first aspect, the decision is transferred to the centralized decision system via the human-machine interface.

In 1 a device according to the invention is shown according to the first aspect, alternative a. A centralized decision-making system 10 is provided as an element for centralized decision-making in the vehicle. A plug-in networking device 12 is connected to this via wire, with the plug-in traffic networking device 12 having the capability of wireless communication for traffic networking. A memory 14 is also connected to the centralized decision-making system 10, in which the results of previous decision-making and information about the traffic network can be stored. An existing human-machine interface 16 is used in alternative a neither to display decisions of the centralized decision system nor to receive user input. A first portable electronic device (PED) 18 and a second PED 20 are connected to the centralized decision system 10. However, the present invention is not limited to this, but only one PED can be provided. The connection between the centralized decision system 10 and the PED 18 or PED 20 can be either wired or wireless. Both the first PED 18 and the second PED 20 have traffic networking capability.

With the device off 1 may provide a method for selecting one of at least two traffic networking devices as the primary device 2A be carried out taking steps S4 and S5a into account.

In step S1, the change in transport mode is detected. A change in the connection, whether wired or wireless, is repeated for each of the devices 12, 18 and 20 can occur, to the vehicle, a change in kinematics, such as a speed of movement unusual for a pedestrian, a change in the use of the PED, such as the launch of a navigation application on the device, and the like.

In step S2, at least two devices that are capable of traffic networking are detected. It can be recorded here that at least two devices with the ability to network traffic connect to the centralized decision system 10 by wire or wirelessly when the distance to the vehicle falls below a certain minimum distance. The portable electronic devices 18 or 20 can also be detected by establishing a wired connection to the vehicle.

According to step S3, skills and/or preferences that are relevant to the traffic networking operation are collected.

According to the first aspect, alternative a, step S4 is executed, which selects the primary traffic networking device. This selection can be made, for example, by transferring a decision that has already been made from the memory 14 to the centralized decision system 10 in the case of a known combination of traffic networking devices and capabilities or preferences. If the combination of traffic networking devices and capabilities/preferences is not known, decision making can be done according to predefined rules and decision logic.

In alternative a, step S5a is next carried out, in which the devices 12, 18 and 20 are informed wirelessly or by wire of the result of the decision made regarding primary traffic networking devices.

This is followed by step S6, in which the decision-making data is saved for future use. For example, the identities of the devices, the capabilities and preferences, and the decision are stored in memory 14.

Step S6 is followed by step S7, in which the traffic networking operation is started, that is, the traffic networking operation is started with the selected device. An example would be using the PED 18 in 1 .

In alternative a of the first aspect, a user is not involved via the human-machine interface 16, which is shown by the cross on the connecting line between the human-machine interface 16 and the centralized decision system 10.

This in 3 The first aspect shown, alternative b, differs from alternative a in that information of a passive nature is sent to the user via the human-machine interface 16. To be more precise, the process consists of: 2A Instead of step S5a, step S5 is carried out in that, in alternative b, the device is informed about the decision in wireless or wired form and at the same time the user is informed about the completion of the process. The human-machine interface 16 can either be a display in the vehicle or the portable electronic device 18, 20 can provide information about the decision.

In the 4 Alternative c shown in the first aspect differs from alternative b in the first aspect in that step S4c is carried out instead of step S4.

In step S4c, the primary traffic networking device is selected. For this purpose, the information on the basis of which a selection of the primary traffic networking device is possible is presented to the human user either on a display in the vehicle or on a display with a portable electronic device such as a smartphone, and is also referred to in this step S4c manual entry of the selected primary traffic networking device by the user into the human-machine interface. This is followed by step S5 from alternative b of the first aspect.

Thus, according to alternatives a, b and c of the first aspect, decision making regarding the primary transport networking device can be carried out without a centralized decision system Participation of the user (alternative a), with passive information from the user (alternative b) or with active participation of the user (alternative c).

As a result, the vehicle or pedestrian can only communicate via a traffic networking device.

First embodiment

The first embodiment of the present invention is described below as alternative d and alternative e with reference to the structures in 1 and 3 and the procedures 2 B and 2C explained.

The first exemplary embodiment of the present invention, alternative d, forms the in 1 shown first aspect, alternative a of the present invention in that the centralized decision element 10 has the functionalities to activate failure detection in order to monitor the functionality of the primary traffic networking device, to detect a failure of the primary device and to inform all devices thereof.

It is preferred if the centralized decision element 10 is further capable of re-detecting devices capable of traffic networking after failure detection.

The method in the first exemplary embodiment, alternative d is in 2 B shown. This procedure differs from the first aspect, alternative a 2A in that instead of step S4, step S4d is carried out, in which the centralized decision element additionally activates failure detection in order to monitor the functionality of the primary traffic networking device, in step S7d the centralized decision element monitors the functionality of the primary traffic networking device begins and in a step S8d in the case in which a failure in the functionality of the primary traffic networking device is detected by the centralized decision element, information about the failure is transmitted to the at least two traffic networking devices by the centralized decision element. A secondary traffic networking device can then take over the function of the primary traffic networking device.

Optionally, in the first exemplary embodiment, alternative d can be used in the method according to 2 B after step S8d, you can return to step S2 of detecting at least two traffic networking devices, as indicated by the dashed arrow. In this case, the new primary traffic networking device is only selected upon repeated execution of step S2.

The first embodiment of the present invention, alternative e, forms the in 1 shown first exemplary embodiment, alternative d of the present invention in that the centralized decision element 10 additionally has the functionalities, furthermore an order for the takeover of the functionality of the primary traffic networking device by the at least one further traffic networking device in the event of failure of the primary traffic networking device and in the event that a failure in the functionality of the primary traffic networking device is detected by the centralized decision element, to activate the next available traffic networking device as the primary traffic networking device based on the stored order.

The method in the first exemplary embodiment, alternative e is in 2C shown. This method differs from the first exemplary embodiment, alternative d, in that instead of step S4d, step S4e is carried out, in which an additional sequence for the takeover of the functionality of the primary traffic networking device by the at least one further traffic networking device in the event of failure of the primary traffic networking device is stored and that instead of step S8d, step S8e is carried out in which, before information about the failure is transmitted to the at least two traffic networking devices by the centralized decision element, the next available one of the traffic networking devices is based on the stored order is activated as the primary traffic networking device.

It is particularly preferred if at least three traffic networking devices are provided and the order for taking over the functionality of the primary traffic networking device includes the determination of a secondary and a tertiary traffic networking device. To this In this way, even after the failure of a first primary traffic networking device and the function of the primary traffic networking device being taken over by the next available traffic networking device, a secondary traffic networking device is still available due to the order, whereby redundancy can still be maintained.

Second aspect

5 shows a device corresponding to alternative a of the second aspect and 6A a method of alternative a. In 8th a method of alternatives b and c of the second aspect is shown, with the device corresponding to alternative b in 7 is shown and the device according to alternative c in 9 .

The first aspect differs from the second aspect in that in the first aspect a centralized decision-making system 10 is provided as an element for centralized decision-making. In the first aspect, the detection of the change in transport mode, that is, for example from one vehicle to another or from a pedestrian to the vehicle or from one vehicle to a pedestrian, is done only by taking into account the change in kinematics, for example in a speed , which is unlikely for a pedestrian, and the change in the use of a portable electronic device, such as launching a navigation application on the device. In the second aspect, decision making based on predefined rules and logic occurs separately on each device with traffic networking capability. The devices exchange their capabilities and preferences regarding transport networking, make local decisions, carry out conflict resolution and, if possible, achieve coordination.

The selected traffic networking device then begins its traffic networking operation. Activities, skills and the selection decision are stored locally on each device.

In the second aspect, the degree of human participation in the decision-making process also differs in alternatives a, b and c. In alternative a of the second aspect, humans are not involved at all and each traffic networking device selects the primary traffic networking device based on predefined rules and logic and performs conflict resolution. In alternative b of the second aspect, humans are not involved in the decision-making process, but are informed about the result via the human-machine interface, for example via a display on the smartphone. In alternative c of the second aspect, the human makes the decision which is then transmitted to the traffic networking devices via the human-machine interface.

The alternative a of the second aspect is discussed with reference to 5 described. As already mentioned, in contrast to the first aspect, no centralized decision-making system is provided, but rather a plug-in traffic networking device 30 with an element 32 for distributed decision-making and a memory 34 is provided in the vehicle. The first PED 40 has a distributed decision-making element 42, a memory 44 and a human-machine interface 46, while the second PED 50 has a distributed decision-making element 52, a memory 54 and a human-machine interface 56. The connection between the element 32, the element 42 and the element 52 can be wireless or wired.

With reference to 6A A method for selecting one of at least two traffic networking devices as a primary device according to alternative a of the second aspect will now be described.

In step S21, detecting the change in transport mode is similar to step S1 of the first aspect. More specifically, the process is repeated on each device and a change in kinematics, such as a change in use of the portable electronic device, is detected.

Step S21 is followed by S22, in which, similar to step S2 of the first aspect, a large number of devices with traffic networking capabilities are detected. This can be done by exchanging information, such as via beacons, between the devices. These beacons can be Bluetooth-based and are used for location identification. The information is preferably collected via a wireless connection.

Step S23 is then carried out, in which, similarly to step S3 for the first aspect, skills and preferences that are relevant for the traffic network are collected. In contrast to the first aspect, information collection is carried out separately on each device and repeated application for each device. If there are known devices with known capabilities and preferences, the selection decision can be read from memory, provided there is appropriate information in memory. When new devices or old devices with new capabilities are present among the preferences, information gathering occurs from the devices.

In the subsequent step S24, the primary traffic networking device is selected. This is done separately on each device. When known combinations of devices and capabilities or preferences are present, decision making occurs in memory. Otherwise, predefined rules and logic are used to make the selection of the primary traffic networking device.

Since the method of alternatives b and c of the second aspect, which is in 8th is shown, in step S26 from the method of alternative a of the second aspect 6A differs, joins in 6A Step S27 immediately follows step S25. If there are conflicts between the plug-in networking device 30 and the first PED 40 and the second PED 50, the conflict is resolved in step S25 and a decision about the primary traffic networking device is agreed on the basis of predefined negotiation rules. In step S27, the data is saved for future use. This is done separately on each of the devices, with device identities, capabilities, preferences and the selection decision to the primary transport networking device being stored locally. Step S27 is followed by step S28, in which, as in step S7 2A of the first aspect, the transport network operation is started.

Thus, in alternative a of the second aspect, the selection of the primary traffic networking device is carried out without user involvement in the human-machine interfaces 46 and 56 of the first PED 40 and the second PED 50, respectively.

Alternative b of the second aspect differs from alternative a of the second aspect in that passive information is provided to the user of the first PED 40 and the second PED 50 via the human-machine interfaces 46 and 56. In the method corresponding to alternative b of the second aspect, step S26 is between step S25 and step S27 8th provided in which the user is informed about the decision regarding the selected primary traffic networking device. More specifically, the human user is informed about the completion of the process, for example via displays of the human-machine interfaces 46 and 56 in 7 . The other steps S21 to 25 and S27 and S28 correspond to the procedure 6A the alternative a of the second aspect.

The alternative c of the second aspect is in 9 shown and differs from alternative b of the second aspect 7 in that an active input is made at the human-machine interface 46 and 56 of the first PED 40 and the second PED 50. In contrast to variant b of the second aspect, in 8th Instead of step S24, step S24c is carried out and instead of step S25, step S25c is carried out.

More specifically, in step S24c, the primary traffic networking device is selected in such a way that, given a known combination of devices and capabilities or preferences, the decision about the primary traffic networking device comes from a memory on which the known combination is stored. Otherwise, in step S24c, the information is communicated to the human user, such as via the human-machine interfaces 46 and 56 in 9 . In step S25c, which is located in 8th Following step S24c in the second aspect, alternative c, the conflict resolution and agreement takes place in such a way that the information about it is transmitted to the human user via the human-machine interface 46, 56 and then the manual input via the human-machine -Interface 46, 56 takes place. In step S26, information about the decision made is provided in the same way as in alternative b of the second aspect.

Second embodiment

The second embodiment of the present invention is described below as alternative d and alternative e with reference to the structure in 5 and the procedures from the 6B and 6C explained.

The second exemplary embodiment of the present invention, alternative d, forms the in 5 shown second aspect, alternative a of the present invention in that at least one of the traffic networking devices 30 and 40 is designed so that it can be set as a watchdog for monitoring the functionality of the primary traffic networking device, can activate failure detection in order to Monitor functionality of the primary traffic networking device, can detect a failure of the primary device and can inform all devices about it.

It is preferred if at least one of the traffic networking devices 30 and 40 is further capable of re-detecting devices capable of traffic networking after failure detection.

The method in the second exemplary embodiment, alternative d is in 6B shown. This method differs from the first aspect, alternative a, in that instead of step S25, step S25d is carried out, in which one of the traffic networking devices is additionally defined as a watchdog for monitoring the functionality of the primary traffic networking device, in step S28d monitoring the functionality of the primary traffic networking device is started and in a step S29d in the case in which the watchdog detects a failure in the functionality of the primary traffic networking device, transmitting information about the failure to the at least two traffic networking devices -Devices are carried out. A secondary traffic networking device can then take over the function of the primary traffic networking device.

Optionally, in the second exemplary embodiment, alternative e can be used in the method 6B after step S29d, return to step S22 of detecting at least two traffic networking devices. In this case, the new primary traffic networking device is only selected upon repeated execution of step S22.

The second embodiment of the present invention, alternative e, forms the in 5 shown first embodiment, alternative d of the present invention in that the watchdog is able to take over the functionality of the primary traffic networking device before transmitting information about the failure to the at least two traffic networking devices or during this transmission. Furthermore, a sequence for the takeover of the functionality of the primary traffic networking device by the at least two further traffic networking devices can be stored if the primary traffic networking device fails. Furthermore, in a case where a failure in the functionality of the primary traffic networking device is detected by the watchdog, the functionality may be present to designate a tertiary traffic networking device as a new secondary traffic networking device.

The method in the second exemplary embodiment, alternative e is in 6C shown. This method differs from the second exemplary embodiment, alternative d, in that instead of step S25d, step S25e is carried out, in which an additional sequence for the takeover of the functionality of the primary traffic networking device by the at least one further traffic networking device in the event of failure of the primary traffic networking device is stored and that instead of step S29d, step S29e is carried out in which, before transmitting information about the failure to the at least two traffic networking devices, the tertiary traffic networking device is used as a new secondary traffic networking device on the basis of the saved order is activated.

In this way, even after the failure of a first primary traffic networking device and the function of the primary traffic networking device being taken over by a secondary traffic networking device, a new secondary traffic networking device continues to be available due to the sequence, whereby redundancy can still be maintained .

With the devices and methods explained above according to the first aspect, the first exemplary embodiment, the second aspect and the second exemplary embodiment, a decision can be made The determination for selecting the primary traffic networking device, which alone can carry out the traffic networking communication with respect to a vehicle or a pedestrian, can be carried out in an effective manner, whereby the redundancy can be improved.

Third embodiment

The third embodiment of the invention is described below with reference to 10 until 14 described in more detail.

Communication units within ITS stations (IST-S) as traffic networking devices, more precisely within an IST-S router, can be a fixed ECU (Electronic Control Unit) or can be consumer plug-in devices. In particular, portable electronic devices, such as smartphones and smartwatches, can be able to take on the function of traffic networking devices.

Numerous frequencies and protocols can be used to operate traffic networking, such as ITS-G5, LTE-V2X as two separate technologies at 5.9 GHZ and New Radio V2X with frequencies in the millimeter wave range. The typical lifespan of vehicles is usually more than 10 years. Rapid advances in V2X technologies and V2X features are expected during this period.

• Eine Vielzahl an ITS-Stationen, die sich als eine Gruppe bewegen, z.B. in einem Fahrzeug, wie z.B. einem PKW oder Bus, können in Bezug auf das C-IST für Unsicherheit sorgen, da statt einem Objekt der Eindruck einer Vielzahl von Objekten verursacht wird. Einerseits kann dieser Eindruck beispielsweise durch ein V2X-fähiges Fahrzeug mit Fahrgästen, die V2X-fähige Telefone mit sich führen, verursacht werden. Andrerseits kann bei zwei Fußgänger, die eine Straße überqueren, von denen einer kein V2X-fähiges Gerät mit sich führt und der andere zwei V2X-fähige Geräte, beispielsweise ein Smartphone und eine Smartwatch, mich sich führt und von denen der letztgenannte die Richtung ändert, bei den Fahrzeugen in dem Bereich der fehlerhafte Eindruck entstehen, dass sich beide Fußgänger noch gemeinsam bewegen, wodurch eine unsichere Situation hervorgerufen wird.

In view of the advantages that can be achieved with the subject matter of the third embodiment, the inventors of the present invention have taken into account the following considerations:

• A large number of ITS stations moving as a group, for example in a vehicle such as a car or bus, can cause uncertainty with respect to the C-IST, as the impression of a large number of objects is created instead of one object . On the one hand, this impression can be caused, for example, by a V2X-capable vehicle with passengers carrying V2X-capable phones. On the other hand, two pedestrians crossing a street, one of whom is not carrying a V2X-enabled device and the other is carrying two V2X-enabled devices, such as a smartphone and a smartwatch, and the latter of whom changes direction, The vehicles in the area give the incorrect impression that both pedestrians are still moving together, which creates an unsafe situation.

When a plurality of ICU stations move as a group with different characteristics and/or different capabilities, a case of low or no utilization may occur when only one of the ICU stations is used as the primary ICU station. This can be the case, for example, if they have different features, such as a smartphone that supports a newer frequency compared to the frequency supported by the vehicle. With regard to different performance capabilities, reference is made to the example that a vehicle can measure speed more accurately than a smartphone. Furthermore, the real-time characteristics can also differ, for example due to the different arrangement of V2X antennas, e.g. in a tractor and in a trailer or semi-trailer.

According to the inventors, it is also conceivable that several ITS stations are combined into a single ITS station for reasons of redundancy or that they are used together. For example, in the case where an ITS station 1 has failed, an ITS station 2 can take over.

Even taking these considerations into account, the inventors of the present invention have come to the conclusion that not only one primary device necessarily represents the best solution for all available functions, but that the primary device is assigned separately for each function and/or sub-function. The functions include, for example, the communication link that can be used for traffic networking, the protocol stack or protocol functionality, the sensor system, such as in relation to vehicle speed, or the message or information type for exchange, such as navigation information, and the processing capabilities of the CPU and/or the GPU.

For example, communication technology may be available in a 2030 smartphone that is not available in a traffic networking unit built into a 2025 vehicle. In contrast, a smartphone can use newer communication technology available, but higher accuracy vehicle data may be available via a traffic networking unit built into a vehicle.

With regard to the third exemplary embodiment of the present invention, it will now be explained how the functionalities offered by a variety of traffic networking devices can be selected and/or combined. The following functions and categories according to Table 1 can be used as examples: Table 1 Category of function Example Examples of performance metrics to exchange Description Transport Network Connection DSRC (Dedicated Short Range Communication) Antenna shielding, antenna arrangement, power output, maximum connection speed, supported protocol versions Communication connections that can be used for transport networking 2.4GHz 5GHz 5G 6G UWB (Ultra Wideband) Processing ability CPU (Central Processing Unit) GPU (Graphics Processor) Available cycles and timing, speed, ASIL level Available general processing capability sensor Speed, position, acceleration, navigation information Accuracy, frequency of updates Source of information Human-machine interface Cluster, smartphone application Is the user active? Interaction with the operator, e.g. confirmation by the user and selection of parameters function Warning that the vehicle has stopped According to a certain standard A functionality Generally Power supply Device type Arrangement Version of hardware and/or software Battery status/Last dec usta nd, Built-in device/End product for consumption/PED, in the pocket/in the hand/Connecting to a cluster Device and device health information

Furthermore, a performance parameter can also be used, such as the computing load, the energy source, the available resources, the signal strength and the accuracy of the signal.

According to the third exemplary embodiment, the first and second aspects and the first and second exemplary embodiments are further developed in such a way that the centralized decision-making system, which is hereinafter referred to as a decision-making element, of the first aspect and the first exemplary embodiment and the decentralized decision-making system, which is also hereinafter referred to as a decision-making element , the second aspect and the second exemplary embodiment are developed in such a way that a function assignment as a primary device takes place for at least two of the functions and / or categories according to Table 1.

• Schritt 1: Zuweisung der Funktion als Entscheidungselement an eine der ITS-Stationen,
• Schritt 2: Jede ITS-Station informiert das Entscheidungselement über die Funktionalität und/oder Version und/oder eine Leistungskennzahl,
• Schritt 3: Das Entscheidungselement weist zumindest zwei Funktionen spezifischen ITS-Stationen (Knoten) zu und
• Schritt 4: Beginn des Betriebes mit den Funktionen.

According to the method of the third exemplary embodiment, the following four steps are preferably carried out:

• Step 1: Assignment of the function as a decision-making element to one of the ITS stations,
• Step 2: Each ITS station informs the decision element about the functionality and/or version and/or a key performance indicator,
• Step 3: The decision element assigns at least two functions to specific ITS stations (nodes) and
• Step 4: Start operating the functions.

It is preferred if in step 3 the matching and overlapping functions are identified, an individual solution is carried out for each function, taking into account the redundancy and the joint consideration of different sensor information, function chains can be identified, e.g. sensor signals are assigned to functions, and the function is output to the communication connections and all devices involved are informed about their assigned functions.

The execution of the mentioned four steps of the third embodiment will be described in more detail with reference to an example from FIGS 10 , 11 and 12 explained. The process for a complex process chain is as follows 13 and 14 shown.

Step 1, in which the allocation of the decision element takes place, is described with reference to 10 explained in more detail.

In a step 1.1 a, the large number of traffic networking devices are detected, in this case an ITS station in the vehicle, a consumer ITS station, a smartphone ITS station, a smartwatch ITS station, another ITS station and a yet another ITS station. Furthermore, in this example there is a CPU (central processing unit) which can, for example, take on the function of a watchdog. In this step 1.1a, each of the traffic networking device is connected to the decision element either wirelessly or by wire when this traffic networking device is in the vicinity of the vehicle.

In the subsequent step 1.1b, the exchange of information between the traffic networking devices and the decision element takes place, for example via beacons, which can be Bluetooth-based, preferably via a wireless connection.

Steps 1.1a and 1.1b can be carried out as in the first and second aspects of the present invention.

In a step 1.2, the capabilities and preferences for each of the traffic networking devices are collected. If known traffic networking devices and/or known preferences are present, then these are obtained from memory. If there are new transportation networking devices or known transportation networking devices with new capabilities and/or preferences, then these capabilities and/or preferences are acquired by the transportation networking devices.

The selection of the primary device among the traffic networking devices as a decision element takes place in step 1.3. If known combinations of traffic networking device and capabilities and/or preferences are present in the form of functionalities, then these are obtained from memory. Otherwise, predefined rules and logic are used to make decisions. These predefined rules and logic may include, but are not limited to: user settings, stable power supply (e.g. charged battery or connection to a power supply), available resources such as calculation cycles, risk rating, which may also include update status.

An example of risk classification is the key component Automative Safety Integrity Level (ASIL) according to ISO26262. ASIL assesses the probability of a potential hazard, controllability and possible accident severity. The risk classifications range from QM, where no special measures can be taken, to the classification from ASIL A to ASIL D. Each of these risk levels represents a risk potential that is ten times higher than the previous level, with ASIL A being the lowest risk level and ASIL D represents the greatest risk level.

In a step 1.4, the traffic networking device is informed about the decision made. This information can, for example, be transmitted wired or wirelessly.

At the end of step 1, the data is stored for future use in a step 1.5, whereby the identities of the traffic networking devices, their functionalities, such as their capabilities, their preferences, and the decision are stored in a central memory, for example in the central element .

In the following step 2, which also refers to 10 As explained, each ITS station informs the decision element about the functionality and/or version and/or a key performance indicator, which is represented by the arrows on the ITS stations.

For this purpose, information about the functionalities is provided in a step 2.1, with all traffic networking devices transferring their functionality to the decision-making element. The functionalities may be organized in groups, for example as shown in Table 1 above. Some or all functionality may have performance metrics associated with it. Static information may be stored in the memory of the decision element and dynamic content may be subject to updating.

In a step 2.2, the decision element can assign a role and processing chains can be put together. The decision element assigns the roles and data flow related to each relevant functionality based on the submitted functionalities, performance metrics and entered requirements using predefined rules and logic.

An example is in 10 the in-vehicle ITS station with DSRC as the type of transport networking connection shown in Table 1 and with functions A and B, the consumer ITS station with DSRC as the type of transport networking device and with function A shown, the smartphone ITS station with 5 GHz shown as the type of transport networking device and with functions A and B, the smartwatch ITS station with 2.4 GHz shown as the type of transport networking device and with functions A and B. For the further ITS station, any type of traffic network connection and the functions B and C are specified, while for the even further ITS station, in addition to any type of traffic network connection and the functions B and n, MFLOPS (MegaFLOPS, where FLOPS is the floating point operations). second) is given as a measure of performance. For the CPU and the decision element, in addition to the functions B and C or only C, the type of traffic network connection and the measure of performance are specified.

From the functional example in 11 It emerges that the CPU can have the function of watchdog with regard to functionality C, which is also present in the decision element, and the CPU can also have the function of watchdog with regard to functionality B, which is also present in the smartphone ITS station , may have. Functionality A, like the entire Smartwatch ITS station, is unused in this example.

In the in 11 In the example shown, the decision element coordinates all functions, indicates "active" that all operations assigned by the decision element are being carried out, indicates "unused" that no operation occurs until the decision element responds and indicates "watchdog" indicates that the decision element or a specific functionality or device is being monitored.

After the mentioned step 2.2. In step 3, the decision element assigns at least two functions to specific ITS stations (nodes). All devices are informed about their roles.

In 12 an example of this is given. In this example, the smartwatch ITS station is unused, a traffic network connection is made via the ITS station in the vehicle, the smartphone ITS station and the further ITS station that serves as a backup, and the calculation is carried out via the CPU and that Decision element carried out. Functionality A is carried out by the ITS station in the vehicle, functionality C is carried out by the decision element with the further ITS station as a backup and functionality n is carried out by the yet further ITS station.

In step 4, the transport network operation begins. During traffic networking operation, it is preferred that the decision element constantly monitors and readjusts the assignment of roles, for example when a battery becomes empty, as an example of a change in the performance indicator, or the transport mode changes.

In the case of a complex process chain in the 13 and 14 According to a further application of the third exemplary embodiment, in steps (1a) and (1b) the raw data, in this case the vehicle speed and the speed based on the GPS data, are transmitted from the ITS station in the vehicle and the smartphone ITS -Station to the CPU so that the CPU can carry out further processing, i.e. a fusion of this speed data, as one functionality. In step (2), the processed information, ie in this example the result of the fusion of the speed data, is transferred from the CPU to the decision element. Assume that based on the result of fusing the speed data from the CPU, the decision element produces a result of functionality X. This result is transmitted in steps (3a), (3b) and (3c) to the interfaces, i.e. in this case to the smartwatch ITS station, ITS station in the vehicle and smartphone ITS station, from which then into the Steps (4a), (4b) and (4c) information is transmitted via the respective transport network connection.

In a further example, not shown in the figures, each interface can, in a first step, carry out a data transmission with regard to nearby users. For example, a vehicle may support DSRC, a cyclist may carry an ultra-wideband phone, and an infrastructure element may have 5G data. In a second step, the data from all sources can then be combined into a model.

Thus, in accordance with the described configurations of the third exemplary embodiment, the considerations of the inventors of the present invention are taken into account that not only one primary device necessarily represents the best solution for all available functions, but that the primary device is assigned separately for each functionality or function and / or sub-function can.
